Optimal collection and preservation protocols for fecal DNA genotyping are not firmly established. We evaluated 3 factors that influence microsatellite genotyping success of fecal DNA extracted from coyote (Canis latrans) scats: 1) age of scat, 2) preservative, and 3) diet content.We quantified genotyping success by comparing rates of allelic dropout, false alleles, and failed amplifications am...

the voltammetric behaviour of sulfadoxine (sdn) was studied at a glassy carbon electrode in 0.2 m phosphate buffer solutions using cyclic, differential-pulse (dpv) and square wave voltammetry (swv). the dependence of the current on ph, concentration, and scan rate was investigated to optimize the experimental conditions for the determination of sdn. the oxidation process was shown to be diffusi...

The buffer cache plays an essential role in smoothing the gap between the upper-level computational components and the lower-level storage devices. A good buffer cache management scheme should be beneficial to not only the computational components, but also to the storage components by reducing disk I/Os. Existing cache replacement algorithms are well optimized for disks in normal mode, but ine...

The IBM S/390 Parallel Transaction Server (PTS) has introduced into the mainframe environment many aspects of distributed client/server processing. This paper begins the investigation of one of those aspects; the impact of in-storage buffer misses as additional processors are added to the complex. Additional processors are seen as a solution to both the capacity and availability problems of lar...

semen collection evaluation and addition of preservatives to increase storage period of sperm are essential for successful artificial insemination. this study was conducted on 4rams (2 ghezel merinos and 2 merinos moghani) to evaluate the effect of two diluents in khalatposhan research station. average age of rams was 3 years. rams were trained to serve the artificial insemination and semen sam...

We report two case studies of aphasic patients with a working-memory impairment due to reduced storage in the phonological buffer. The two patients display excellent performance in phonological discrimination tasks as long as the tasks do not involve a memory load. We then show that their performance drops when they have to maintain fine-grained phonological information for sentence comprehensi...

Continuous etching of aggressive all-in-one adhesives occurs in wet dentin tubules after polymerization of the adhesives. This study challenged the hypothesis that unpolymerized acidic monomers from an aggressive all-in-one self-etching adhesive continue to etch beyond dentin hybrid layers. Dentin surfaces bonded with Adper Prompt L-Pop were sectioned into 0.3-mm-thick slabs. Some of the slabs ...

A novel design of molecular buffer for molecule storage and delivery using a PANDA ring resonator is proposed. The optical vortices can be generated and controlled to form the trapping tools in the same way as the optical tweezers. In theory, the trapping force is formed by the combination between the gradient field and scattering photons, which is reviewed. By using the intense optical vortice...

The emergence of clustered and networked storage architecture gives rise to a new type of servers which act as data conduits over the network for remotely stored data. These servers, which we call pass-through servers, are mainly responsible for passing the data through them without interpreting it in any way. In this paper, we put forward a scheme of network-centric buffer cache management. Th...

For distributed and network applications, efficient management of program state is critical to performance and functionality. To support domainand application-specific optimization of data movement, we have developed the Internet Backplane Protocol (IBP) for controlling storage that is implemented as part the network fabric itself. IBP allows an application to control intermediate data staging ...
